You are on Windows. Every AI browser launch event seems to happen on a Mac first.
Atlas launched Mac-only. Dia is Mac-first with Windows perpetually “coming soon.” You are left watching keynote demos for software you cannot install.
Here is the thing nobody says on stage: you do not need their browser. You need AI where your work already happens — and on Windows, that means an overlay, not another window.
How many times today have you Alt-Tabbed to a chatbot and lost the thread of what you were doing?
That trip is the tax. On Windows, where Alt-Tab is practically a lifestyle, the tax compounds.
Curious what that switching costs you? Try the Focus Points Calculator — it measures how much of your day gets eaten by app and tab switching.
Why Windows Gets AI Browsers Last
AI browser startups chase Mac-first launches. The reasons are boring and practical: homogeneous hardware, developers who all use MacBooks, a press corps that screenshots in light mode.
Windows users get the leftovers: Electron ports six months late, missing features, or “join the waitlist” pages. The pattern held for Arc, for Dia, and for Atlas at launch.
Waiting is a strategy with a cost. Every month you wait is a month of Alt-Tabbing to chatbots.
The 5 Real Options on Windows
#1 — SiteQuest (Overlay, Any Model)
SiteQuest does not ask you to switch browsers. It floats over Windows — any app, any window — summoned with Shift-Space. ChatGPT, Claude, Gemini, or 100% offline local AI via Ollama.
- Best for: AI access without leaving work. Research, writing, coding lookups.
- Price: Free core; Plus $3.99/mo; Pro $6.99/mo.
- Windows support: Native. Not a port, not a waitlist.
#2 — Comet (Full AI Browser)
Perplexity’s Comet runs on Windows with citations and agents. If you want one browser to live in and you do citation-heavy research, Comet is excellent.
- Best for: Deep research sessions with sources.
- Trade-off: It is still a browser you must switch into.
#3 — Edge + Copilot (Built In)
You already have it. Edge’s sidebar and Copilot cover quick questions without installing anything. Shallow, but zero friction.
- Best for: Nothing to install, casual use.
#4 — Brave + Leo (Private)
Brave runs great on Windows with Leo AI and built-in ad blocking. Strong pick if privacy outranks AI depth.
#5 — ChatGPT / Claude Web Apps (Pinned)
Pin the web apps to your taskbar. Free, but every lookup is still an Alt-Tab round trip.
